15mm to 12mm hub conversion

[Charity85]

Good day Hubbers

I threw my anthem carbon 27.5 wheelset on my gravel bike, everything is compatible so far other than front hub being 15mm thru axle and my bike being 12 mm. I saw the following product https://www.velofuze.com/thru-axle/15mm-thru-axle-adapter-to-12mm-thru-axle/ can any recommend it or something similar? Do they work? Not damage the hub? Lastly anyone know where to source it locally?

Thanks and happy new year

The sleeve adapter should work fine, alternatively depending on what make of hubs you have one could try and see if there are replacement end hub caps to convert from 15mm to 12mm.

Hey. I have used 9mm sleeve in the past and they work ok but would suggest getting adaptors. 

 

Giant hubs are normally DT swiss so you just need new end caps

Good luck - can be a puzzle solving the end cap situation but LBS should be able to assist

I've had a few of these done .my machine shop makes a new sleeve to fit the original bearings and modify the end caps. Quite easily done

I've done over 6000km on my gravel bike wheels using similar sleeve reducers - 15mm to 12mm thru-axle.

Can't remember what brand they are, I ended up buying them in Canada and having a friend bring them over. Super simple and easy solution.

A quick revive anyone where I can source this locally?

An engineering shop will make one for you quickly and easily.

I have, in the past, used an alu pipe with a 15mm OD and 1,5mm wall thickness. Cut, file and off you go.

I couldn't find any locally so made my own

Bump, hope hubbers returning from holiday can assist

[TomR]

I got mine from Grant at Sprocket and Jack. He will have a solution for you.

Did you end up solving or sourcing a part?

I had a shop in Brackenfell fabricate a reduction sleeve that fits inside the 15mm ID DtSwiss axle. Works like the proverbial bomb.

New Engineering, try them. This is basically what @Jewbacca did.

There's zero risk to this mod. End caps are increasingly difficult to source.

Jip the gents from Sprocket and Jack engineered me endcaps, worked perfectly

[two hands]

If it’s any help I found www.forkmods.com has plenty of solutions. Converted my OPEN UP from 15 to 12mm. Shipping was quick and easy.

quite pricey for those kits - did you find this cheaper more oem than just re-lacing your wheel onto the right hub?

this would work great, but sometimes the end caps themselves need to be adapted (the rockshox SID has something it must have inherited from the RS-1 days that i need to remove to use on another bike)

Ja, I see they're $130 AUD now. I think it was closer to $100 when I ordered a couple of years back with a more favourable forex rate too. I have some pretty special (and hard-to-come by) ENVE hubs laced to ENVE rims. So yes, cheaper than a new hub and wheel rebuild! 🙃

Also have a 15mm hub wheelset I want to use on my gravel bike. Found these guys that make vesconite sleeves with OD 15mm and ID 12mm. For the rpice its a huge bargain.
